Research Interests: Agnotology; history and philosophy of science related to climate change and the communication of science.

My name is Thiago Medaglia. I am a science and environmental journalist from Brazil, and the founder of Ambiental Media (, where we transform science into compelling and accessible media products. I am former editor of National Geographic Brasil magazine. As a reporter, I've been traveling to remote places in my country to cover stories at the intersection between conflicts over land use, deforestation, and the impacts of climate change on biodiversity and for traditional populations. The fascination with science and the natural world, and the proximity to scientists, followed me from the first steps in journalism and the interest in research – although always present – was intensified more recently, after a one year Knight Science Journalism Fellowship at the Massachusetts Institute of Technology (KSJ at MIT).


I coauthored 5 books about environmental topics; was a fellow at the International Center for Journalists (ICFJ, 2015); received an advanced certificate in Entrepreneurial Journalism from the City University of New York (CUNY, 2016); and was a speaker in the last two editions of the World Conference of Science Journalists (WCSJ, 2017 and 2019). Most recently, I completed AM History of Science degree at Harvard University, where I worked with Professor Naomi Oreskes.

My interest has been in ignorance (Agnotology): its epistemology, the deliberate production, the political strategy to discredit science, and the rise of belligerent political leaders. I am also interested in documenting the dismantlement of science in Brazil, and in studying fields of history and philosophy of science related to climate change and the communication of science.
